Networks are only as good as the
foundation they’re built on.
Ensure that your customers’ structured cabling system is installed
to the highest level of quality, or your network will not be as good as
it could be.

Fiber Testing
• How to know if your premise fiber is
good
4
NETWORKSUPERVISION
What Exactly Is a “Good” Fiber?
• Look to the standards for guidance
• TIA/EIA-568-B.1 describes a good
fiber based upon its application
– Horizontal cabling
– Backbone cabling
– Centralized cabling
The BICSI Telecommunications
Distribution Methods Manual (TDMM)
references ANSI/TIA/EIA-568
5
NETWORKSUPERVISION
Recognized Fiber Types
• Horizontal
– Multimode fiber, 50/125 or 62.5/125 micron
• Centralized
– Multimode fiber
coating
cladding
core
• Backbone
– Multimode or single-mode fiber
• Component performance specified in
TIA/EIA-568-B.3

TIA TR-42.8 Action on Testing
• Create an information document to
specify testing and explain the proper test
procedures
– TSB140, “Additional Guidelines For FieldTesting Length, Loss And Polarity Of Optical
Fiber Cabling Systems “
– The scope describes field testing of length,
optical loss and polarity, in optical fiber
cabling using an optical loss test set (OLTS),
optical time domain reflectometer (OTDR) and
a visual fault locator (VFL)
11
NETWORKSUPERVISION
Proposed Two-Tier Testing
• Tier 1: OLTS
– Conform to TIA-526-14A and TIA-526-7
• Most closely simulate system
– Verify polarity using OLTS or VFL
• Tier 2: Tier 1 plus OTDR trace
– Evidence that cable is installed without
degrading events (e.g., bends,
connection, splice)
12
NETWORKSUPERVISION
Fiber Test Equipment
How to test
13
NETWORKSUPERVISION
Premise Fiber Testers
•Visual light sources
•Fiber microscopes
•Optical loss test kits
•Optical time domain reflectometers
•Certification test sets
•Integrated test platforms
•PC software tools
14
NETWORKSUPERVISION
Microscope
• Visually inspect the endface
of fiber connectors under high
magnification
– 200X to 400X most common
• Check connector condition
– Cleanliness and scratches
• Either directly view the
endface or view a video image
transmitted from a camera
onto a display
15
NETWORKSUPERVISION
Critical Fiber Optic Parameters
• Dirty connector endfaces were cited as the
number one problem encountered during
the fiber installation process.
• Dirty and poor quality endfaces yields high
optical attenuation
89 out of 100 network owners and
contractors cited dirty connector
endfaces as the number 1
problem.
16
NETWORKSUPERVISION
What does dirt look like
• Dirt can migrate from a dirty to a clean connector
17
NETWORKSUPERVISION
Inspect active equipment too
• The connectors in active equipment
(routers, switches, NICs) get dirty too
• Do not overlook these connections
– Video probes allow simple and safe inspection
of active network equipment ports
Add
switch
18
NETWORKSUPERVISION
Optical Loss Test Set
• A light source and power
meter
• Measure the insertion loss
(attenuation) of a fiber link
• Source: LED’s or lasers at
measurement wavelength
• Meter: matched to dynamic
range and wavelength of
source
• Light source(s) and meter
can be integrated into 1 box
• Hand-held and light weight
19
NETWORKSUPERVISION
Loss Certification Test Set
• Master/slave pair of
optical loss test sets
• Automated insertion loss
and length measurement
and instantaneous
standards-based Pass
analysis
• Each unit = optical
source(s) + meter + CPU
• Often tests multiple fibers
in single operation
• Hand-held and light
weight
20
NETWORKSUPERVISION
Fiber Optic Mandrels
Fluke Networks’ Multimode Fiber Mandrels
offer a simple, cost effective way to:
Improve the repeatability and
consistency of multimode optical power
and loss measurements when using a
LED source.
Ensure that your measurements are
compliant with TIA/EIA-568-B standards.
Guarantee the correct number of wraps
around the proper diameter mandrel.
Protect the 3.0 mm fiber cable from
damage and unwanted micro bends.

56
NETWORKSUPERVISION
Engineered For Network Owners
• Reduce stress and uncertainty by
– Knowing that your network was thoroughly tested
• 100 Mb/s to the desk and higher speed backbones taxes
fiber infrastructure and requires rigorous testing
• Demand Tier 2 certification for a complete view of the
fiber plant with both insertion loss certification and
OTDR trace
– Having the diagnostic tool you need to restore
your network should problems arise
• Minimal training (ease of use, novice-friendly UI)
• Minimize network problem diagnosis and
troubleshooting time (channel map, OTDR, inspection,
ease of use)
57
NETWORKSUPERVISION
